Thomas & Betts Corporation

I'll research this company to verify its profile.

Thomas & Betts Corporation (commonly "T&B") was founded in 1898 by Robert M. Thomas and Hobart D. Betts and grew from a New York City electrical-conduit agency into a manufacturer of electrical connectors and components. It incorporated in 1917, moved its headquarters to Memphis, Tennessee in 1993, and was a New York Stock Exchange–listed company until ABB Ltd acquired it for $3.9 billion ($72/share) in 2012, after which its shares ceased trading. Reported size at the time of the deal was roughly 8,750 employees and about $2 billion in 2010 revenue. T&B remains a subsidiary-brand business unit of ABB (renamed ABB Installation Products Ltd. in 2018); the Memphis operation employed about 1,500 people plus regional plants.

Products/operations: T&B designs and manufactures electrical connectors, fittings, and components for industrial, commercial, communications, and utility markets — conduit fittings (Liquidtight, Erickson couplings), wire and cable connectors, terminals, cable ties (T&B invented the cable tie in 1958; Ty-Rap brand), cable tray, metal framing (Kindorf, Superstrut), grounding products, boxes and enclosures, emergency lighting, and highly engineered steel transmission structures. It also produced commercial/industrial HVAC equipment under the Reznor brand, which ABB sold to Nortek in 2014. Legacy operations were organized into Electrical, Steel Structures, and HVAC segments. This is clearly an operating company, not an NPE.

Patent-litigation posture: T&B appears in the tracked data only as a defendant (0 plaintiff, 2 defendant cases), consistent with an operating company defending product suits rather than asserting a portfolio. Both tracked suits were brought by competitor John Mezzalingua Associates, Inc. d/b/a PPC (an East Syracuse, NY coaxial-connector maker): one filed in the Eastern District of Texas (2010-11-09) and one in the Western District of New York, Rochester (2011-06-30), the latter naming Belden, Inc. as a co-defendant. These are competitor-versus-competitor disputes over coaxial cable connector technology, not NPE assertions.

Context: The dispute traces to PPC's patent U.S. 5,470,257 ("Radial Compression Type Coaxial Cable End Connector"). A related earlier PPC case against T&B reached the Federal Circuit (John Mezzalingua Assocs. v. Thomas & Betts Corp., 54 Fed. Appx. 697 (Fed. Cir. 2003)), and the parties also appeared in ITC Investigation No. 337-TA-650 on coaxial cable connectors.
